The date picker UI is considered more essential than the time picker UI. Thus we are re-prioritizing our work to focus on the date picker instead. The time picker UI will be disabled by default and can be turned on via pref.

Based on the input from product and UX, it seems that the date picker should be prioritized over the time picker. I will pref off the time picker for now and focus on the date picker instead. Mike, wonder if you could review this small patch? I created a “dom.forms.datetime.timepicker” pref that defaults to false. When datetimebox is clicked, it checks if type is "time", and if the pref is true or false. Thanks!
